Sync with latest packaged version from Debian 9. Effectively this
only updates comments and disabled options, but having less changes
to look at during an apt upgrade is nice and reduces the chance of
adding errors.
There are currently no nginx.org builds for Debian 9, so we need to
use the package from Debian's repository. This package provides a
www-data user and group instead of an nginx one.
We can revert some of this after Debian 9 is released and official
builds come from nginx.org (though it might be useful to keep the
main nginx.conf as a template).
Debian 9 is still in beta and doesn't have nginx.org builds yet, so
we need to use the nginx package in Debian's repositories, and that
required a bit of a different configuration.
After official nginx.org builds are released we can revert this.
I'm surprised this worked all these years actually. Since Ansible
version 1.6 it has been possible to use the version_compare filter
instead of doing math logic on strings.

I realized the other day that due to complex logic in the location
blocks, various WordPress static files like images and stylesheets
didn't get the HTTP Strict Transport Security header set. We need
to include it on each level where we are setting headers, because
nginx overwrites headers if you set them again in a child block.
There was some knowledge floating around that 860 bytes was the
optimal size, I think it was from an Akamai engineer or something,
but the HTML 5 Boilerplate server configs use 256 bytes, and I
actually have HTML content that is less than 860 bytes, so I guess
I could benefit from compressing it. gzip compression is costly
for the compression side, but very quick for the client, so this
is a good thing.

The variable name is misleading as this really does is install the
certbot client and its dependencies, and we generally want this to
always happen. If a host doesn't want it, they can override it in
their host vars.
Perhaps I should rename this variable to "bootstrap_letsencrypt" or
something so it is more accurate.
The `ConditionFileIsExecutable` goes in the [Unit] section! This
fixes the error:
systemd[1]: [/etc/systemd/system/renew-letsencrypt.service:6] Unknown lvalue 'ConditionFileIsExecutable' in section 'Service'
Only vhosts running WordPress, etc need PHP. Make sure to set the
appopriate variables for each vhost in the host's vars, ie:
nginx_vhosts:
- domain_name: example.com
has_wordpress: True
- domain_name: example.net
needs_php: True
You can set either of them, but not both—needing WordPress implies
needing PHP.
Used to indicate if a vhost needs PHP configuration or not, like
for a static site. Set in the hosts's nginx_vhosts block. Defaults
to "False" if unset.
This reverts commit 201165cff6.
Turns out this actually breaks initial deployments, because the
cache gets updated in the first task, then you add sources for
nginx and mariadb, but it doesn't update the indexes because the
cache is < 3600 seconds old, so you end up getting the distro's
versions of nginx and mariadb.
When you give Ansible the key id it will check if the key exists
before trying to download and add it. I got the long fingerprint
from `sudo apt-key finger`.
